ditto - Memory Fault

From within a ksh window (in photon), when i use ditto command, depending on
the size of the window, ditto fails and return with a Memory Fault or a
SIGSEGV; i found that a 66 rows X 160 columns works fine; however if i add a
single row, runs ditto and make CTRL-E (+wait 2 seconds), ditto crashes.

66X160 = 10560 bytes ???

Is there a workaround according to have larger windows and running ditto
properly ?
